    Amongst recent computer books, this is a rarity. There seems to be only 1 diagram in the entire book. No GUIs to pretty up the scene. In this sense, the book is a throwback to those texts of the 80s. Strictly command line and file I/O. Bash under linux is shown by the book to be not that different from an earlier Bourne shell. Or even the more rudimentary C shell. The various chapters discuss such items as defining variables and thence using these to build up expressions in a script. Burtch methodically shows how to increase the complexity of your scripting. If some of you come from an earlier unix background, and have scripted there, then the book is reassuring. It should validate that most of your expertise carries over into bash and linux. Sure, there might be some new material. But the book shows that a typical script is not that different from a unix script of 20 years ago.
